MENZO A. RUTENBER, OF COLLINSVILLE, OKLAHOMA.

ROLLER-DOOR EQUIPMENT.

Application filed April 25, 1918.

To all whom it may concern:

Be it known that I, MnNZo A. BU'rnNnnn, a citizen of the United States, residing at Collinsville, in the county of Rogers and State of Oklahoma, have invented certain new and useful Improvements in Roller- Door Equipments, of which the following is a specification.

This invention relates to door hangers and has for its object the production of a simple and efieient door hanger, the supporting rollers of which. are efficiently shielded so as to prevent the accumulation of ice or other foreign substance within the hanger.

Another object of this invention is the production of a simple and eflicient means for supporting a door whereby the door will be permitted to freely move without being obstructed in its travel.

With these and other objects in view this invention consists of certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

In the drawings Figure 1 is a side elevation of the door and supporting means therefor,

Fig. 2 is aside view of the door, the supporting hangers being shown in section,

Fig. 3 is a section taken on line 33 of Fig. 1,

Fig. 1 is a section taken on line H of Fig. 1,

Fig. 5 is a section taken on line of Fig. 1,

Fig. 6 is a side elevation of one of the upper hanger wheels used in connection with the present invention.

referring to the drawing, it will be seen that 1 designates a supporting frame having a door opening 2. A door 3 is slidably mounted upon the frame 1 and is suspended from an upper hanger casing 4. the lower end of the door being supported upon a lower track frame 5.

The upper hanger frame 1 comprises an inner plate 6 which inner plate is provided with an outwardly extending flange 7 upon the bottom edge thereof. An outer plate 8 is fitted over the inner plate 6 and is provided with a flange portion 9 along the upper edge thereof through which flange portion 9 passes a suitable securing means such as a bolt 10 for firmly holding the ianger 41. upon frame 1. The plate 8 Specification of Letters Patent.

isspaced from the inner plate 6 and is provided with an inwardly extending flange 11 upon the lower edge thereof,.which flange 11 is spaced from the edge of the flange? for producing longitudinally extending slot 12 through the bottom of the casing i.

Hanger straps 15 are secured to the pins 11' and are placed between the wheels 1% and those hanger straps 15 are provided with widened lower ends 16 which widened lower ends 16 are firmly secured to the door 3. It of course should be understood that any suitable number of hanger members may be employed without departing from the spirit of the invention.

- The door .3 carries a bottom plate 17 along the lower edge thereof and this bot tom plate is substantially Z-shaped and conforms to the shape of the lower end of the door 13 as shown in Fig. 5 of the drawings. This plate 17 is provided with a depending flange 18 which flange 18 is adapted to rest in close proximity to the frame 1. Suitable supporting rollers 19 are carried by the casings 20, which casings 20 are fitted within the socket 19 formed in the lower end of the door 13. The rollers 19 extend through suitable apertures 21 formed in the transversely extending portion of the substantially Z-shaped bottom plate 17 as shown clearly in 5 of the drawings. The substantially Z-shaped bottom plate 17 is provided with a depending portion 18, which depending portion-18 is adapted to fit snugly in engagement with the brackets 20 mounted upon the side of the frame 1 as shown clearly in Fig. 5. These brackets 20 support suitable angle-iron plates 22 arranged in inverted relation, the transversely extending portion of the angle-iron plates 22 constituting a track upon which the rollers 19 work. It will therefore be seen that a very simple and eflicient means has been produced for facilitating the sliding movement of the door upon the angle-iron track 22. As shown in Fig. 6 aspecial de sign of the roller as illustrated and this roller has its edge rounded in cross section is clearly illustrated in Fig. 6 and it should be understood that this roller may be constructed in any desired design without departing from the spirit of the invention.

A stop plate 2% is carried by the support 1 and is adapted to limit the rearward movement of the door 3 as the same is moved to an open position. A. suitable lock-=- ing hasp is carried by the door 3 and its over a locking lug 26 of the locking plate 27.

This locking plate 27 carries a locking pin eflicient operation of the hanger device.

What is claimed is A sliding door construction of the class described comprising a support, a door, an upper hanger frame carried by said support, rollers carried by said door and adapted to work upon said upper hanger, said door provided with pockets formed in the lower edge thereof, casings fitted within said pockets, a roller mounted within each casing and projecting below the outer edge of said casings, a substantially Z-shaped shield plate extending across the bottom edge of the door and having apertures formed therein through which said last mentioned rollers project, said substantially Z-shaped plate also extending upwardly against the outer face of the door and projecting clownwardly along its opposite edge and adapted to normally lie snugly against the outer face of said support, a plurality of brackets carried by said'support and provided with outwardly extending end portions, a substantially inverted L-shaped plate secured to the outer faces of said brackets and having an inwardly extending flange constituting a track for receiving said last mentioned rollers, and said downwardly extending flange of said Z-shaped plate projecting down below the upper face of said substantially inverted L-shaped plate for a considerable distance.

In testimony whereof I aflix my signature in presence of two witnesses.
